Just saw the thread from a couple of days ago about casting Locust Swarm only once to not overwrite the first and save mana. My only real question about this build now is, how many times should you cast Haunt in order to maximize damage? I was having mana issues before because I was casting LS multiple times. Mana is no longer an issue if casting LS only once, so I can spam Haunt as much as I want, but how many times is optimal? Thanks.
